ADDING MACHINE.

Application filed. March 16, 1922. Serial No. 544,085.

3 Massachusetts, have invented new and useful linprovementsm Adding Machines, of

which the following is a specification.

This invention relates to an adding ma chine which includes a carriage carrying a J rotary platen, and adapted to be automatically reciprocated endwise, as in a so-called shuttle machine, when such reciprocatlon is desired, the type of machine to which the invention relates being well known under the name of the ales adding machine.

A machine of this type includes well known mechanism whereby the machine may be converted from an adding to a non-adding machine, and vice versa. In the Wales machine this conversion is effected by the simple operation of shifting a d changing the height of a convertlng cross shaft which is adapted, when shifted downwardly, to render the adding mechanism operative, and, when shifted upwardly, to render the adding mechanism inoperative, the machine being operable in one case to print and add, and in the other case to print without adding. Hcretofore, the said converting shaft has been shifted manually.

lily invention has for its ch ief object to pro- .vide moans-for causing the machine to add when the platen is at one end of its reciprocating movement, and is in position to permit the printing of figures on the edge portion of the record. sheet. at the right hand of the operator, and for rennering the machine incapable of adding when the platen is'at the opposite end of its reciprocating movement, and in position to permit the printing of figures on the portion of the sheet at the left hand of the operator. i V

' he invention is en'lbodied in the improvelllOE'll'f-j hereinafter described and claimed.

Mounted to turn looseadapted to engage the carriage-rod i0 and move the same sidewise to a rear position, thus rendering it inoperative, or preventing it from imparting rotation to the platen The above-described carriage-reciprocate in mechanism may be installed in a machine not provided with means for automatically reciprocating the carriage and platen, in the manner described in my former application.

In Figures 1 and 1 I show the usual converting shaft 8, through the shifting of which the machine is converted from an adding to a non-adding machine, and vice versa, said shaft and the mechanism (not shown) with which it cooperates being well known elements of the Wales adding machine. Since my invention is embodied in the mechanism hereinafter described, for shifting theshaft 8, I do not deem it neces sary to show and describe the elements with which said shaft cooperates.

The converting shaft 8 is movable vertically in guides 4V, in the frame ol, and is provided with trunnions t from which depend rods or struts a. W hen the shaft 8 is lowered, as shown by Figure 1 the machine is operable to print and add, and when the shaft is raised, as shown by Figure 1, the machine is operable to print without adding. l

The shaft 8 is supported in its non-adding position as usual, by the engagement of the lower end of the struts u with the notched studs o, and by the engagement with the trunnions t of oscillatory hookedlatch arms w, pivoted to a cross shaft 00 journaled in the frame cl Heretofore the shifting of the shaft 8 from the non-adding position to the adding position has been performed by manually displacing the latch arms to and the struts u from the positions shown by Figure 1, to those shown by Figure 1 To raise the shaft 8 to its non-adding-position, it has been necessaryto depress a non-adding key (not shown) located in the top of the machine, said key being connected to the shaft in in such manner that when the key is depressed, a clockwise partial rotation of the latch arms to is caused. placing the arms in the position shown in Figure 1. Tolower the shaft 8 to the adding position, it has been necessary to depress an, adding key (not shown), located in the top of the machine. and similarly connected to the shaft 00, but arranged in such a manner that when the said key is depressed, it will cause an anti-clockwise movement of the arms 10.

The mechanism in which the present i.n vention is embodied, is organized to cause the machine to add when the platen is at one end of its reciprocating movement, and is in position to permit the printing of figures on the edge portion of the record sheet, at the right hand of the operator, and to render the machine incapable of adding when the platen is at the opposite end of its reciprocating movement, and in position to permit the printing of figures on the portion of the sheet at the left hand of the operator. To accomplish this result the carriage cam 16 is provided at one end with a segmental cam 67, arranged to contact with, and displace a trundle-roll 68, constituting an element of mechanism for swinging the latch-arm w to either of the positions shown by Figures 1 and 1*. Said ,mechanism, as here shown, includes a movable bearing piece 69 at the upper side of the base plate 12, carrying the roll 68, a slide 70, at the lower side of the base plate, and rigidly connected with the bearing piece by a rivet 71, which is movable in a slot (not shown) in the base plate,

the bearing piece 69 and slide 70 being guided by studs 72 and 73, fixed to the base plate and passing through slots 72 and 73*.

spring 80, attached at one end to the slide, and at its opposite end to a stud adjustably connected with the lower end of the lever 79. Said lever is pivoted at 81 to a fixed ear 82, on the frame d, and its upper end is connected by a link 83 with the swinging end of the latcharm w. The function of the spring 80 is to press the roller 68 toward the axis of the carriage cam 16, and hold it in the path of the cam .67. I provide means, however, for rendering the spring inoperative to perform this function, said means being embodied in a rotatable member 84, journaled in the lower end of the upright lever 7 9, and carrying the pin 80 with which the spring is connected, said member having a knurled knob 85 by which it may be turned to locate the pin 80, either in the position shown by Figures 2, 3 and 8, to exert tension on the spring 80, and render it operative, or in the position shown by Figure 4-, to slacken the spring and render it inoperative; A stop pin 86, on the. lever 79, cooperates with a stop finger 87 on the member 84, in main taining tension on the spring.

It will now be seen that when the spring 80 is operative. contact of the cam 67 with the roll 68 will cause the latch arm 10 to swing forward to the position shown by Figurel, and hold up the converting shaft- 8 in the non-adding position, and that when the cam 67 recedes from the roll 68. the

spring 80 moves the latch arm to permit the shafts to drop to its adding position. When the spring; is made inoperative, as indi cated by Figure 4:, the latch arm remains in the position shown by Figure l.
